gcc's ATTRIBUTE_UNUSED is a hint and not a requirement - it means
'suppress the warning if I don't use this', but not 'tell me if I
mistakenly used it anyways'. Therefore, it is safe to blindly mark a
variable ATTRIBUTE_UNUSED even if it ends up being used, it just looks
funny.
Ah, I see. It may give the programmer a false sense of security about
something or other though (I haven't taken the time to mentally
articulate exactly what, but something ;-)
